Abstract

International organisations active in Africa are often criticised for their ineffectiveness. So too is the European Union (EU), which is also accused of failing to assume a more prominent conflict management role in war-torn countries. This article examines the EU’s capacity and readiness to take on such a role in one such country, the former Republic of Sudan, home to Africa’s longest-running civil wars and the first ‘genocide’ of the 21st century. It begins by outlining the EU’s record in Darfur and the North–South Peace Process. Drawing upon 25 interviews and Hill’s ‘capabilities–expectations model’, it then questions whether the EU’s ‘capabilities’ (resources, instruments, unity) were ‘fit for purpose’ in Sudan’s hostile target setting. It concludes by identifying settings that have been more propitious for a conflict-related management function and by suggesting that the EU should better manage expectations about future security roles.  相似文献

Even though previous research has not examined mass murder prior to 1965, scholars have asserted that the mid-1960s marked the onset of an unprecedented and ever-growing mass murder wave. Using news accounts and the FBI's Supplementary Homicide Reports (SHR) as sources of data, this study analyzes 909 mass killings that took place between 1900 and 1999. Although the mid-1960s marked the beginning of a mass murder wave, it was not unprecedented, because mass killings were nearly as common during the 1920s and 1930s. The results also show that familicides, the modal mass murder over the last several decades, were even more prevalent before the 1970s. Moreover, mass killers were older, more suicidal, and less likely to use guns in the first two-thirds of the 20th century. Although some have claimed that workplace massacres represent a new “strain” in mass murder, the findings suggest that the only new type of mass killing that emerged during the 20th century was the drug-related massacre.  相似文献

The analysis of fingerprint chemical composition is a meaningful way to excavate the multidimensional information of fingerprint, including the donor profiling information and the age of a fingerprint, which broadens the evidential values of fingerprint, especially for the partial and distorted fingerprint. But the research remains still in the pilot phases or is ongoing. Amino acids are the dominant organic substances in latent sweat fingerprint and influenced by many donor factors. Hence, their content reflects personal information of donors. Forensic science will be revolutionized if suspects can be individualized by their amino acid content. The diverse nature, distinct physicochemical properties, and ultra-micro levels of amino acids present in fingerprints make it hard to detect. A high sensitivity method for detecting and quantifying multiple amino acid components is required. UHPLC-QqQ MS/MS offers high sensitivity, high separation, simultaneous multicomponents detection, and no derivatization, making it an ideal method for detecting and analyzing amino acids in fingerprints. Therefore, in this study, we propose and validate an efficient UHPLC-QqQ MS/MS method for the extraction and analysis of 13 amino acids from fingerprint. We compared the results of amino acids of 10 different substrates and found that the inherent amino acids in most porous substrates would have been extracted along with the fingerprint amino acids, making them unsuitable for quantitative amino acid analysis. Instead, plastic sheets are ideal substrates for laboratory studies. Then, extensive experiments were conducted among 30 donors for multidimensional information analysis. The type of samples analyzed were eccrine-rich fingerprints. A Binary Logistic Regression (BLR) model was developed, and the female and male donors were successfully differentiated by amino acids in fingerprints. Two other mathematical models were also developed to verify the accuracy, and all three different mathematical models were able to identify donors of different genders with over 90% accuracy. This demonstrates that amino acids have the potential to provide more information for donors as metabolic markers. In the future, we will conduct a series of experiments to analyze more multidimensional information for individual identification by amino acid content in the fingerprint.  相似文献

The purpose of the present note is to advance two theoretical claims. The first claim proposed is that the impact of the availability of oversight tools and of the most broadly understood legislative capacity (availability of material, technical, financial resources; availability of well-trained staff) on the effectiveness with which legislative oversight is performed is conditional. The second claim put forward, after reviewing a rich body of work on executive–legislative relations and legislative oversight in West Africa, is that, of the various conditions that promote or prevent the effective use of oversight tools and capacity, political will is the single most important. These claims have both theoretical and practical relevance, for if political will is as important as is claimed for the effective performance of the oversight function, then international organisations may have to reconsider their approach to legislative strengthening.  相似文献

Abstract

This article explores the relations to Africa and African decolonisation of three key figures in Brazilian critical geographies and development studies, Manuel Correia de Andrade (1922–2007), Josué de Castro (1908–1973) and Milton Santos (1926–2001). Based on an analysis of their works and unpublished archives, I argue the radical Third World perspectives these intellectuals expressed anticipated later critiques of development as a neocolonial device. Drawing upon current literature on decolonisation, international conferencing and anti-racist solidarity networks, I discuss these matters in relation to these authors’ interest in cultural diversity and internal colonialism. Crucially, they developed this sensitivity in the Brazilian Northeast, a region especially shaped by Afro–Brazilian and Indigenous cultural legacies. While supporting anti-imperialist nationalisms in the Third World, these Brazilian scholars fostered multilingual, internationalist and cosmopolitan activism and scholarship. This is revealed by the study of the transnational networks they developed during exile and the various persecutions that many of them suffered after the 1964 military coup. Finally, I argue these works can substantiate recent claims to ‘decolonise’ geography and development studies, on the condition that these fields of study take seriously their anti-imperial traditions and their ‘voices from the South’.  相似文献

Abstract

Most of the literature on state transformation focuses on China’s relations with African, Asian and Latin American countries and the National Oil Companies’ overseas expansion to show that China has become fragmented, decentralised and internationalised. This article contributes novel findings by focusing on China’s relations with Europe and the actions of China’s National Nuclear Companies (NNCs). It shows that NNCs, which have become relatively autonomous actors, often pursue their agendas of expansion into Europe without much coordination with, or even in contradiction to, other ministries’ agendas and interests, especially the Ministry of Foreign Affairs. Instead of being orchestrated by the central government, their expansion reflects considerable disorganisation and sometimes undermines China’s official strategy. The article demonstrates this through case studies of NNCs’ involvement in the UK and Romania.  相似文献

Abstract

This paper examines China’s engagement with Africa through economic zones (EZs). It moves beyond the conceptualisation of EZs as undifferentiated enclaves of foreign investment to a dynamic perspective on the locally negotiated process of zone development. Such a perspective entails critical unpacking of the specific zone regime to understand the diverse and evolving relationships among different state and non-state actors. Drawing upon empirical research on the Eastern Industrial Zone (EIZ) in Ethiopia, we explore the complex process of learning and adaptation by government, developers, investors, and workers throughout the development of a zone regime, with specific attention to capital–labour and expatriate–local relations. We find that despite the EIZ being a state-level cooperation project, private Chinese developers work diligently with the Ethiopian government to improve the institutional support for EZs. Chinese investors also collectively generate a management regime to enhance their overseas operational capacity and experiment with various tactics to transform local recruits into an industrial workforce. Local workers, with limited protection by official labour unions, turn to individual- and group-based agency to improve their working conditions. Despite the momentum created by multiple stakeholders, there are concerns regarding the long-term contributions of EZs to engender sustained industrial transformation and skills development.  相似文献

The patterns of cooperation between regions and urban spaces are no longer influenced, to the same extent, by national borders. Political integrative events changed the extent of transborder urban cooperation in the Baltic borderlands, a region that has undergone extensive changes. A social network analysis of cooperative ties in the form of town twinning indicates that the end of the Cold War strongly changed the network of town twinning in this region, whereas the effect of the various EU enlargement rounds seems to be more nuanced.  相似文献

While canines are most commonly trained to detect traditional explosives, such as nitroaromatics and smokeless powders, homemade explosives (HMEs), such as fuel–oxidizer mixtures, are arguably a greater threat. As such, it is imperative that canines are sufficiently trained in the detection of such HMEs. The training aid delivery device (TADD) is a primary containment device that has been used to house HMEs and HME components for canine detection training purposes. This research assesses the odor release from HME components, ammonium nitrate (AN), urea nitrate (UN), and potassium chlorate (PC), housed in TADDs. Canine odor recognition tests (ORTs) were used with analytical data to determine the detectability of TADDs containing AN, UN, or PC. Headspace analysis by gas chromatography/mass spectrometry (GC/MS) with solid-phase microextraction (SPME) or online cryotrapping were used to measure ammonia or chlorine, as well as other unwanted odorants, emanating from bulk AN, UN, and PC in TADDs over 28 weeks. The analytical data showed variation in the amount of ammonia and chlorine over time, with ammonia from AN and UN decreasing slowly over time and the abundance of chlorine from PC TADDs dependent on the frequency of exposure to ambient air. Even with these variations in odor abundance, canines previously trained to detect bulk explosive HME components were able to detect all three targets in glass and plastic TADDs for at least 18 months after loading. Detection proficiency ranged from 64% to 100% and was not found to be dependent on either age of material.  相似文献

The storage and use of explosives is regulated at the state and federal level, with a particular focus on physical security and rigorous accounting of the explosive inventory. For those working with explosives for the training and testing of explosive-detecting canines, cross-contamination is an important concern. Hence, explosives intended for use with canine teams must be placed into secondary storage containers that are new, clean, and airtight. A variety of containers meet these requirements and include screw-top glass jars (e.g., mason jars). However, an additional need from the explosive-detecting canine community is secondary containers that can also be used as training aids whereby the volatiles emitted by explosives are emitted in a predictable and stable manner. Currently, a generally accepted method for the storage of explosives and controlled emission of explosive vapor for canine detection does not exist. Ideally, such containers should allow odor to escape from the training aid but block external contaminates such as particulates or other volatiles. One method in use places the explosive inside a permeable cotton bag when in use for training and then stores the cotton bag inside an impermeable nylon bag for long-term storage. This paper describes the testing of an odor permeable membrane device (OPMD) as a new way to store and deploy training aids. We measured the evaporation rate and flux of various liquid explosives and volatile compounds that have been identified in the headspace of actual explosives. OPMDs were used in addition to traditional storage containers to monitor the contamination and degradation of 14 explosives used as canine training aids. Explosives were stored individually using traditional storage bags or inside an OPMD at two locations, one of which actively used the training aids. Samples from each storage type at both locations were collected at 0, 3, 6, and 9 months and analyzed using Fourier Transform Infrared (FTIR) Spectroscopy and Gas Chromatography–Mass Spectrometry (GC–MS) with Solid-Phase Microextraction (SPME). FTIR analyses showed no signs of degradation. GC–MS identified cross-contamination from ethylene glycol dinitrate (EGDN) and/or 2,3-dimethyl-2,3-dinitrobutane (DMNB) across almost all samples regardless of storage condition. The contamination was found to be higher among training aids that were stored in traditional ways and that were in active use by canine teams.  相似文献
